Implemented the ' (apostrophe) and " (double-quote) text-show operators:
- ' string: Move to next line (T*) then show string (Tj)
- " aw ac string: Set word_spacing=aw, char_spacing=ac, then execute '
Changes:
- Added leading, char_spacing, word_spacing fields to TextMatrix
- Implemented next_line() to use leading (T* operator)
- Added TL, Tc, Tw operators to process_with_mode()
- Fixed " operator in both process_with_mode() and execute_internal() to
actually set word_spacing and char_spacing
- Added tests for all acceptance criteria
